Himshikhar Mazumdar

Himshikhar Mazumdar is a Research Associate at the GIScience Research Group of the Institute of Geography in Heidelberg with a background in Physics specialized in Astrophysics from the University of Heidelberg. His research focuses on estimating traffic volumes using neural networks, estimating vehicle velocity using satellite imaging and using OSM for highway road network analysis, vandalism detection etc.

Research Interests
  • Big Spatial Data Analysis
  • Neural networks and Machine Learning
Projects
  • Geco Project: Estimating traffic volumes using neural networks & machine learning
  • PITS: Planetary Image Traffic Speeds: Using Planet satellite images to estimate traffic velocity on highways
  • OSM road monitor use case: We are investigating the access to education across countries globally. This analysis relies on a) the OSM road network and b) the location of education facilities (e.g. primary schools) in OSM.
  • OSM road monitor: Road data updates are essential for navigation, logistics, and emergency response, but official and commercial sources often have slow update cycles.
    - OpenStreetMap (OSM) provides rapid updates, as seen in disaster scenarios, but issues like vandalism, satellite data processing delays, and infrequent verification still limit its effectiveness.
    - Many routing algorithms struggle with continuously changing data, reducing efficiency and requiring less optimal methods like Dijkstra's algorithm.
